IOT based Water Quality Assurance System

Project Title

IOT based Water Quality Assurance System

Project Area of Specialization Internet of ThingsProject Summary

IOT based water quality assurance system is based upon testing the water quality for drinking purpose. As drinking water varies from place to place, depending on the condition of the source water from which it is drawn and the treatment it receives, but it must meet EPA (Environment Protection Agency) regulation. The traditional method of testing Turbidity, pH and Temperature is to collect samples manually and then send them to a laboratory for analysis which takes more time to get the results. However, it has been unable to meet the demands of water quality monitoring today. So a set of Monitoring of Turbidity, pH and Temperature of water quality will be developed. Our contribution will be if the water quality is abnormal, the data will be sent to the monitoring center and alert the survey staff at the same time. It is convenient for management to take corresponding measures timely and be able to detect the real-time situation of water quality remotely.

Project Objectives

The water quality assurance system will obtain the following objectives:

• Will show results on the Android application (survey staff) and sends a report through the internet to the website (water purification department or water resources research center).
• The main purpose of the device will be to analyze the physical and chemical parameters of the water.

1. PH scale.
2. Turbidity.
3. The temperature of water.

• Will provide the GPS location of the area where the quality of water is poor to the water purification department or to water resource research center.

Project Implementation Method

The methodology of the proposed system (See Figure) will have different aspects in which the work is to be done.

1. Hardware implementation and coding.
2. Data collected from the sensors by microcontroller to check quality of water.
3. Then microcontroller transmits data and display on the application.
4. Result will be stored in database then displayed on Android application.
5. Transmitting result and location of the area to water purification department or water resource research center.

Benefits of the Project

We will develop and design a low-cost water quality monitoring system that can monitor water quality in real time using IoT and android. Introducing a system that will check the quality of water and will send notification through GSM to the water quality analyzer or department of water purification. It will analyze and notify the various water quality parameters such as pH, turbidity and temperature.

If multiple these devices are installed at differnet places will help in monitoring water quality at these places easily.

Technical Details of Final Deliverable

Overview:

IOT based water quality assurance system will be an advanced water quality monitoring system. As the laboratory water testing is based upon collecting the samples of water from areas for which water quality is to be analyzed, the three-step testing is performed physical properties, chemical properties, and biological properties testing of water.  The traditional laboratories method of water quality assurance having problems of complicated methodology, long waiting time for results and sometimes in-accuracy. With the frequent passage of time, more advancement is being made. New technologies are introduced to minimize the disadvantage of lots of time consumption.

Specifications:

• The proposed system will be secure as it does not contain any harm to human life. It has an automatic data storage which can help in doing research and analysis on water quality.
• The proposed system must be reliable in case it can be operated in real environment it can provide precise readings of water and must decide water quality on the basis of these readings.
• The systems will response within maximum 5 minutes depends upon signals strength of the service provider. The device is specified to get few parameters of water its performance can be increased by adding more sensors related to biological and chemical readings of water.
• The wrong results can lead to the wrong use of sensors or the power not provided properly to the device whereas the application can have the issue of internet access only.
• The system will be portable.

Requirements:

The functional requirements of IOT based water quality assurance system are stated below:

1. The system must be able to show water quality to the user in real time.
2. The system must be able to take water readings and process them according to the WHO (World Health Organization) standards.
3. The system must be able to digitize data and store it in database.
4. The system must be able to show the location of current area at which water quality is to be tested.
5. The system must overcome the issues of carrying water samples and preservation, expert’s scarce, chemical reagents and cost of specialized equipment’s.
